Tomato landraces are regaining interest in Spain because their great fruit quality and value in popular gastronomy. Muchamiel is a traditional tomato variety grown in SE Spain that has been recently improved by the CIAGRO-UMH Tomato Breeding Group, resulting in several lines and hybrids with genetic resistances to virus and most of the original Muchamiel genome. In the current study, two hybrids and one pure line from CIAGRO-UMH and a commercial Muchamiel were grown under conventional conditions to evaluate three different grafting treatments: non-grafting and grafting onto the commercial Beaufort and Maxifort rootstocks. The yield parameters and fruit quality were assessed, and a sensory analysis was performed to evaluate the behavior of every scion/rootstock combination. Overall, significantly worse yield and fruit number in Maxifort-grafted plants were reported; as well as a slight reductions in SSC, fructose, and sucrose; and significant effects on few sensory traits. Instead, B...

Kangaroo mother care (KMC) is a multifaceted intervention for preterm and low birth weight infants and their parents. Short- and mid-term benefits of KMC on survival, neurodevelopment, breastfeeding, and the quality of mother-infant bonding were documented in a randomized controlled trial (RCT) conducted in Colombia from 1993 to 1996. The aim of the present study was to evaluate the persistence of these results in young adulthood. From 2012 to 2014, a total of 494 (69%) of the 716 participants of the original RCT known to be alive were identified; 441 (62% of the participants in the original RCT) were re-enrolled, and results for the 264 participants weighing ≤1800 g at birth were analyzed. The KMC and control groups were compared for health status and neurologic, cognitive, and social functioning with the use of neuroimaging, neurophysiological, and behavioral tests. The effects of KMC at 1 year on IQ and home environment were still present 20 years later in the most fragile indivi...

Objectives The aim of this study was to investigate drug release from a double steroid prodrug, OPN501, which incorporates a phenylpropionate linker, and its phenylacetate analogue. The prodrugs, which were designed to deliver prednisolone to the colon for the treatment of inflammatory bowel disease, are based on a novel design that requires sequential azoreductase activity and cyclization of an amino ester to trigger drug release. We sought to explain the divergent effects of the two compounds in anti-inflammatory models and to justify the selection of OPN-501 for clinical development. Methods The compounds were incubated in mouse colonic contents (10%) fermented in brain heart infusion under anaerobic conditions. The disappearance of the prodrugs and release of prednisolone was monitored by HPLC. We then developed a method for assessment of prodrug activation using suspensions of Clostridium perfringens, an anaerobe from the human colon. The cyclization of the compounds was studie...
